Left Over cruising means you get a great deal because you are joining in on the last sector or more than one sector of a continuation of a cruise.
800 passengers left the Zuiderdam in San Diego on May 8th. Those that boarded there, I felt like, we intruded on their last leg of their cruise. Many Canadians and British were on board and settled into their daily routine of onboard life when in comes 800 beginner cruisers, burly "so what" cruisers and those that like to get away to revisit their great times on board previous cruises.
My biggest disappointment is that the cruise line did not emphasis the dress code on board. Fat guts hanging out, shorts, unkept beards, loud and unsophisticated unsavvy "deal finders. Well, we found the deal too, but knew what to do when we boarded!
Zuiderdam cabin 8101 was in a quiet hall right next to elevator shaft.
